Francisco Xavier Castellanos Insuasti
I am a Master of Science in Biology student at the Ray Lab, skilled in cellular and molecular biology, bioinformatics and fieldwork. My research encompasses studies from the evolution of Transposable Elements and the innate immune response of bats, to the Ecology, behavior and habitat occupancy of large mammals: Andean bears, tapirs and Andean foxes, using GPS data collected in several National parks in Ecuador.
